How to set local variables?

Setting local variables in a Linux shell (such as Bash) is straightforward. Local variables are only accessible within the shell session where they are defined. Here’s how to set them:

Steps to Set Local Variables

Open a Terminal: Start by opening your terminal.
Define a Local Variable: To create a local variable, simply assign a value to a variable name without using the export command. Ensure there are no spaces around the equals sign (=).

Syntax:
```
VARIABLE_NAME=value
```
Example:
```
my_var="Hello, World!"
```
Access the Local Variable: To access the value of the local variable, use the echo command with a dollar sign ($) before the variable name.
```
echo $my_var
```
This will output:
```
Hello, World!
```
Scope of Local Variables: Remember that local variables are only available in the current shell session. If you open a new terminal or run a new shell, the variable will not be available.

Example of Setting and Using Local Variables

# Set a local variable
greeting="Hello, User!"

# Access the local variable
echo $greeting  # Outputs: Hello, User!

# The variable is not available in a new shell session

Summary

To set a local variable, use the syntax VARIABLE_NAME=value without export.
Access the variable using echo $VARIABLE_NAME.
Local variables are only available in the current shell session.
